https://safirsoft.com D-Wave announces new hardware, complexes, and software for quantum computing

In addition to the standard roadmap, D-Wave will attempt to build portal-based systems. Most of the effort goes to gate-based computers, which allow you to perform logical operations on discrete qubits. These are well understood in theory and can perform various calculations. But it is possible to build gate-based systems from a variety of qubits, including photons, ions, and electronic devices called transmitters, and companies have grown around each of these hardware options.

But there is a separate type of computation called quantum firing, which involves processing a set of interconnected qubits. Annealing has not been very effective in theory, but it seems to fit the category of optimization problems. And when it comes to appliance cooking, there is only one company called D-Wave.

Now, things get even more confusing. On Tuesday, D-Wave released its roadmap for future processors and software for quantum annealing equipment. But D-Wave is also announcing plans to develop its own portal-based hardware, which will run in parallel with the Quantum Aniller. We spoke with CEO Alan Baratz to understand all the announcements. Annealing

The easiest part of the ad is understanding what happens to a D-wave quantum annealing processor. The current processor, called Advantage, has 5,000 qubits and 40,000 connections between them. These connections play a major role in the performance of the chip, because if there is no direct connection between the two qubits, other connections must be used as a bridge, thus reducing the number of lower bits more effectively.

Starting this week, D-Wave cloud service users will have access to the updated version of Advantage. The qubit and connection stats will be the same, but the device will be less affected by system noise (technically, its qubits retain their coherence longer). “This performance update will allow us to solve larger problems with greater accuracy and greater accuracy due to some of the new manufacturing processes we are using,” Baratz told Ars. He said the improvements were made through changes in the process of making qubits and the materials used to make them. Usually, for optimization problems, this means that the device does not find the best solution, but finds something close to it. So the noise reduction in the new processor means that the device is likely to find something close to the absolute optimum level.

In the future of the next system, the long-awaited Feature 2 will be even greater. Next year or next, this increase will increase the number of qubits to more than 7,000. But connectivity is also increasing exponentially, with D-Wave targeting 20 connections per qubit. Baratz told Ars.

More Than Just Hardware

D-Wave offers a suite of development tools called Ocean. In previous iterations, Ocean allowed people to step back from hardware control. Possible Problem Expressed as Dual Binary Optimization (QUBO), Ocean can optimize the commands needed to handle all hardware configurations and optimally run the problem.D-Wave refers to this as a hybrid problem solution, because Ocean uses classic arithmetic to optimize QUBO before implementation.

The only problem is that all those who may not be interested in testing D-Wave hardware, know how to express their problem like QUBO, and thus the new version of Ocean, by allowing the problems to be Send them to the system in a format typically used by people who want to solve this kind of problem, layer by layer.” “You can now define problems in a language that data scientists and data analysts understand,” Baratz promised. Do D-Wave devices increase their problems or not?Baratz explained Gateway Hardware believes optimization will likely be a correct approach, citing Draft Journal reports that the architecture of some optimization problems for gate devices may be computationally expensive to the point that they can compensate for any achievement of quantum devices. But it is also clear that gate-based devices can solve a range of problems that a quantum hardener cannot. Devices based on electronic qubits are called transmitters. This includes the amount and size of hardware needed to send control signals to the qubits, and the ability to pack the qubits densely enough that they are easy to connect but not close enough to interfere.

One of the problems with D-Wave faces is that the qubits it uses for its throwers are not useful for gateway based systems. While they use the same device (Josephson junction), the solid qubits cannot be adjusted up or down. Gate-based qubits must be processed in three dimensions. So the company plans to make flow qubits, which are also based on Josephson's formulations but use them differently. Therefore, at least some of the company's engineering expertise still has to be used.

Is it the rest? There's no way to know without building hardware, and Baratz said the first experimental qubits are at working temperature as they speak. He was also conservative about computing qubits after the device was ready for public use, saying, "I won't guess until we build and measure."
